Application filed August 12, 1911. Serial No. 643,687.

To; all whom 'it mary concern.

Be it known that l, RA E. STUMP, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State ot' Ohio,have invented certain new and useful Improvements in Signal-Horns,

' ot' which the following is aspecilication.

My invention relates to improvements in signal horns, and isparticularly designed and adapted for use as an exhaust blown signalhorn for use in connection with automobiles, motor trucks, motor boats,and the like. lNhen used as an exhaust blown signal horn in connectionwith automobiles, the same isgpreferably connected to the exhaust pipebetween the engine and the muffler, and when so used the improved hornis adapted to provide a combined signal horn and cutout valve, therotary valve beingadapted to be movedfrom its normal or nondivertingposition to either a fluid diverting cut-out position, or a fluiddiverting horn sounding position, as desired.

The primary object of the invention is to provide a generally improvedcombined signal horn andcut-out valve of this class of exceedinglysimple, cheap, and eticient construction, adapted to be readilyconnected to the exhaust pipe between the engine and the mnler. l

A. further object is to provide an exhaust blown signal horn having itsparts arranged and combined whereby the same may be readily operated andreducing their tendency to sticlt or to become clogged or covered withsoot or carbon to a minimum.

A `With the above mentioned and other ends in view, the inventionconsists in the novel construction, arrangement,- a'nd combination ofparts, hereinafter described, illustrated in one oits embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this' specification, Figure1, is a top plan view of the improved signal horn and :asA

valve, the parts being shown in their normal or nondiverting positions,whereby the liuid or exhaust gases are passed directly into the mu'ler.Fig. 2, a side elevation-of the same. Fig. 3, a vertical longitudinalsectional-view taken on line 3-3 of Fig. 1 the parts being shown intheir liuid diverting Whistle or horn sounding positions. Fig. 4, across sectional view taken on line 4--4 of Fig. 3. Fig. 5, a perspectiveyiew of the rotary valve detached. Fig. 6, a perspective View of therotary hood detached.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

..lhe improved signal horn and valve comprises a two-part vilve and hornbody 1,

terminating at its o posite ends in reducedpipe Dinlet and outletportions 2, and 3, rcspectlvely, adapted to be suitably connected` toand to form a part of the exhaust pipe leading from the engine to themuliler, the two parts of the valve and horn body being provided withattaching Hanges 1a. The valve and horn body is provided with a whistleslot Al, and a crossinember or par' tition 5, interposed between andsecured'to the attaching flanges l, by means ot attaching bolts and nutsG. The cross member 5, is provided with a centrally located iuid dischare valve opening 7, and a tluid discharge ot 8, the latter being locatedat the rear of the whistle slot 1, and being adapted to discharge theoperating fluid to the lip 4a, thereof for sounding the horn in a wellknown and understood manner.

As a means for openingand closing the fluid discharge opening 7, arotary valve 9,

is provided, saidvalve being provided with oppositely extending wingsadapted to ex.- tend on opposite' sides of the cross member 5, and beingpvotally mounted upon a pivot bar or shaft 10, the latter being mountedin suitable bearings 11, formed betweenthe attaching lianges l, of thevalve. and horn body l.

As a means for operating the rotary/valve 9, whereby the same may beth/rowh` into a ii-uid diverting cut-out position' or iiuid divertinghorn sounding pos1tion,one end of the pivot pin or shaft 10, `.isprovided with a crank arm' 12, connected to a wircor cable 13, leadingto suitable operating mechanism, the other end of the cranklarm l12,being 'conneet/ed to a spring 14, whereby the rotary valve 9, will bereturned to and will be normally held in its normal or nondivertingpdsition, as illustrated in Figs. l, and 2, of the drawings. l

` As a means for opening and closing the whistle 'slot 4, when therotary valve 9, is

moved to its closed or nondiverting position or to its vopen or fluiddiverting positions, respectively, a rotary hood15,'is pivotally mounted4upon bearing lugs 16, of the horn body, said hood being provided withsegmental sides forming tone modifying elements adapted to cooperatewith the whistle slot 4, in controlling the pitch andv tone of the hornwhen the latter is being operated or sounded by the passage of theoperating fluid or exhaust gases through the fluid Adischarge slot 8,leading to the lip 4, ofthe Whistle slot, as illustrated in Figs. 3, and4, of the drawings.

As a means for simultaneously actuating slot taking over and coperatingwith a guide pin 19, carried upon one side of the hood 15, whereby thelatter may be operated in an obvious manner. l

From the foregoing description, taken in connection WithA theaccompanying drawings, the operation and advantages of my A inventionWill be readily understood'.

Having thus described one of the embodiments of my invention, what Iclaim and ing cut-out position.

desire to secure by Letters Iatent' is,

1. In a signal horn and valve, a valve and horn body comprising tWo lparts, one vof which is provided With a whistle slot, a cross memberprovided with a valve opening and a fluid discharge slot leading to saidWhistle slot, a rotary valve adapted to open and close said valveopening, and means for moving said rotary valve to a fluid divertingwhistle sounding position or a fluid divert- 2. A signal horn,comprising a horn body provided with a Whistle slot, a cross memberprovided with a rotary valve and a fluid discharge slot leading to saidWhistle slot, a rotary hood adapted to extend above and to open andclose said Whistle slot, and connecting mechanismfor operating saidrotary hood when said rotary valve is actuated.

3. In a signal horn' and valve, the combination lwith a horn-and valvebody provided With a Whistle slot, a cross member having a slot, a crossmember valve openingand a iiuid discharge slot and a rotary hood adaptedto extend above and to open and and horn body, and connecting mechanismadapted to open and close said Whistle slot las said rotary valve ismoved to its closed and open positions, respectively.d

4. In a signal horn and valve, avalve and horn body provided with aWhistle slot and comprising two parts each part consisting of a iangedbody and a reduced pipe portion,- a cross member interposed between saidanged bodies: and provided With a fluid discharge slot and a valveopening, and

a rotary valve adapted to open and close Isaid fluid discharge valvevopening and adapted to be moved to a liuid discharge cpt-outposition'With respect to said Whistle s ot.

5. A signal horn, comprising a vtwopart valve and horn body providedWith a Whistle provided with a valve opening and a fluid discharge slotleading to said Whistle-slot, arotary valve adapted to open and closesaid valve opening, and a rotary hood connected to said valve andadapted to open and close said whistle slot when said rotary valve ismoved to its closed and open positions, respectively.

6. A signal horn, comprising a valve and horn body provided with aWhistle slot, a cross member provided with a liuid discharge slotleading to said Whistle .slot-, a rotary valve adapted to be moved to aliuid close said Whistle slot; of -a ro-` tary valve mounted in saidvalve opening'` diverting cut-out position-With respect to i saidWhistle slot, and a hood connected to said rotary valve and adapted toopen and extend above said Whistle slot When said rotary valve i'smovedto its iiuid diverting IRA E.
